摘要： A multi-stage gear shift transmission comprising a plurality of forward stage gear trains capable of being alternatively established, and a reverse stage gear train having an idle gear portion meshed with a reverse input gear and a reverse output gear. The forward stage and reverse stage gear trains are provided between an input shaft and an output shaft parallel to the inut shaft. A reverse stage establishing clutch mechanism is interposed in the middle of the reverse stage gear train. The idle gear portion is divided into a first idle gear meshed with the reverse input gear, and a second idle gear meshed with the reverse output gear and capable of being connected to the first idle gear through the reverse stage establishing clutch mechanism. The reverse stage establishing clutch mechanism comprises a sleeve which is engaged with the first idle gear for relative non-rotation and for axial relative movement and which is capable of being meshed with the second idle gear, a braking member which is disposed between the first and second idle gears for axial movement so that it may be urged toward the second idle gear in response to the movement of the sleeve toward the second idle gear and which is capable of being rotated in unison with the first idle gear, and a stationary part fixedly disposed to temporarily frictionally engage with the braking member when the braking member is moved toward the second idle gear.

摘要： A multiple-disk clutch apparatus including an input-side rotatable member having a clutch disk pressing surface, a pressure plate attached to the input-side rotatable member and disposed on an axially rear side opposing the pressing surface, a plurality of clutch disks disposed between the pressing surface and the pressure plate with an intermediate plate being interposed between the clutch disks, and a stopper member for restricting an axially rearward return position of the intermediate plate at the time of clutch disengagement. The stopper member is mounted on the input side rotatable member via a one-way mechanism which allows an axially forward movement of the stopper member but which restricts an axially rearward movement thereof. A holder for holding the one-way mechanism can be mounted on the input side rotatable member so as to be movable axially rearward against a spring. A restriction portion for restricting an axially forward movement of the holder can be formed in the input side rotatable member. A shock absorbing member can be interposed between the restriction portion and the holder.
